Specification of Letters Patent.

Patented July 30, 1907.

Application fil d January 18,1902, Serial No. 90,327. Renewed $eptember 5, 1902. Serial No. 122,206.

To all whom it may concern:

Be it known that I, OSCAR IIAMMERSTEIN, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new an d useful Improvements in Cut ting Apparatus, of which the following is a specification.

My inventionrelates to cutting apparatus which is specially adapted for cutting cigar wrappers and analogous flimsy material.

I am aware that heretofore machines have been devised and constructed for cutting cigar wrappers, but these machines have for the most part been provided with a die having an upright cutting edge all ol whose parts were in substantially the same horizontal plane and over whose edge a roller was passed, to cut the leaf by downward pressure in the manner in which an ordinary punch or die is commonly operated. I have found, however, that in the machines constructed according to that principle, the cutting while fairly even along portions of the die which presented a straight edge to the roller, was in many cases wholly ineflicient along portions of the die edge which were curved or irregular. This, however, while it constituted a great defect in machines of that character, nevertheless en-' by cutting the wrapper, not by direct pressure againstthe sharpened edge of the knife in the form of a die, but by pressing a suitable traveler laterally against the edge of a plate or other sheet support and producing relative movement between the said support and traveler so as to cause the traveler to run around the said edge.

In the accompanying drawings I have shown a suction box provided with an elevated plate and also in another figure provided with apertures at the sides, the sides and top of the box forming a unitary structure, and for the travelers I have shown balls which are the best means at present known to me for carrying out my invention.

In the accompanying drawing I have shown by way of illustration a cutting apparatus in which one form of my invention is embodied, it being understood that my invention is not limited thereto.

In these drawings, Figure I is a plan view of a cigar wrapper cutter showing the main operative parts of a machine in which my invention is embodied; Fig. II is a side view thereof; Fig. III is an edge view showing the interaction between the edge of the suction box or wrapper cutter and the cooperating balls; Fig. IV is a side viewoi the cutter arm with yieldingly supported balls; Fig. V is an end view thereof; Fig. VI is an underneath plan view Figs. VII, VIII and IX are diagrammatic views showing the mode of operation of the device; Fig. X is a plan view of a combined suction box, wrapper cutter and rolling table; and Fig. XI is a sectional side elevation of the same, showing means whereby the rolling table may be raised and lowered.

In the drawings a indicates a suitable suction box, shown in the present instance as of the general shape of a cigar wrapper and (in Figs. II and III) provided with a perforated wrapper support or suction plate I) suitably supported so as to leave a narrow space 0 for the influx of air for a purpose presently to be explained.

(I and e are suitable balls. These balls are carried rotatively as will be described and rotate on the axes 00-90 and cooperate with the edge or corner f of the suction plate or cutter b. The balls d e are carried respectively on rods or spindles gh. Each of the rods or spindles 9 his carried upon an arm L rigidly secured to a hub j, pivotally carried upon a stud supported by bracket 1 rigidly carried by the arm m. This arm m is in the present instance pivoted in the rear of the machine and is or may be provided with a suitable handle 0 by which it may be manipulated, it being un derstood, however that nothing herein contained shall be construed to limit the present invention to a manually operated machine, or to exclude a machine operated by power.

A suitable leaf spring 9 bears against a flattened portion q of the hub j and operates in conjunction with the spring r to restore the ball d or e to a normal position shown in Figs. IV, V and VI. This spring 7' is secured at one end to a stud on the arm s carried by the hub j and at the other end to a fixed stud ten the frame of the arm m.

The end of the arm m which carries the balls is shown as traveling in an are about a center as clearly shown in Fig. IX and as it travels the balls d e are caused to run around the edge of the suction plate of the suction box a.

Examination of Fig. III will develop the fact that the balls run on the corner or lateral edge of the suction plate I).

I have found by long experience that a die having a vertical cutting edge does not cut the leaf satisfactorily, whether a plunger be employed to come down upon the die, or traveling rollers which press downwardly upon the upwardly extending cutting edge be employed. I have found that in employing such structure some portion of the leaf-is not properly cut and it is necessary for the operator to press away the deioctively cut portion of the leaf with his thumb. These objections I obviate by employing what, for the lack of a better term, I call a lateral cutting edge.

In the present instance it is shown as a corner and wherever I use the term lateral or laterally either with respect to the cutting edge or the travelers I mean to be understood in this sense; namely, an edge extending laterally rather than vertically of the travelers, or in line with the movement of the plunger. I also, in the specification and claims, employ the terms cutter and cutter member in analogous senses inasmuch as the cutter member is a cutter so long as it is one member of the cutting device In Figs. VII, VIII and IX, I have shown in diagram the travel of the balls. In these figures the arm is supposed to be moving in an upward direction on the sheet as indicated by the arrows. The ball 0 contacts with the edge of the suction plate, let us say, at the point 1 and as the arm travels the hub 9' will swing on its pivotal mounting and the ball e will travel around the edge of the suction plate in the (li rection indicated by the arrow 2, the arm carrying the ball trailing behind the pivotal point on. which its carrier arm is mounted to turn. The ball (I will under these circumstances strike the edge of the suction plate at about the point 3 and will travel in the direction of the arrow 4 over such edge. Thus on the movement of the arm in one direction, the part of the suction plate between. the points 1. and 3 will be traversed once by each ball. The balls (1 and e are pulled against the edge of the suction plate or cutter by the springs T which thus cause the said balls to exert a lateral pressure in a direction parallel with the plane of said cutter. As the arm m travels the hall 6 will be the first to leave the plate I) and this will take place at or about the point 5. Subsequently the ball (2 will leave the plate I) at or about the point 6, so that between the points 5 and 6 both balls will traverse the suction plate. The arm m may now make a return stroke, the ball d contacting with the suction plate at or about the point 6 and passing in the direction of the arrow 7 and the ball 0 contacting at or about the point 5 and passing in the direction of the arrow 8. The arm m continues to travel and at the proper moment the ball (1 passes off the suction plate at or about the point 1. It will thus be seen that in case of necessity while a single wrapper is on the suction box, all parts of the edge of the wrapper where the cutting takes place are traversed at least twice by a ball and on the sharp curves, to wit, at the ends of the plate are traversed four times by the balls, thus insuring a very eficient cutting.

The detailed mode of operation is as follows: The wrapper is spread out smoothly upon the suction plate I) and pressed around the edge thereof, and side of the suction box, so that the air suotion will act not only over the entire surface of the suction plate, but by acting in the narrow space between the suction plate and the suction box will hold the edges of the leaf firmly around the edge of the suction box. Relative movement may now be produced between the balls and the suction box 'in any desired manner, as the balls traverse or are traversed over the edge f of the suction box the wrapper will be cut into the desired form. This wrapper may now be manipulated or disposed of in any desired manner.

It will be understood that while I have referred to the balls as traveling I do not necessarily mean to restrict myself to moving the balls with respect to the suction box or plate, but desire to include within my claims such equivalent structures as may be justified by the state of the art.

In Fig. XI, I have shown a suction box at having a perforated top suction plate 1) forming therewith a unitary structure having a corner f, and have provided a series of apertures it around the box below the top to subserve the function performed by the slot or opening 0 shown in Figs. II and III. Surrounding the suction box is a suitable table 1). This table 12 has connected therewith a yoke to which is adapted to be actuated by a rod y which rod may be raised or lowered in any suitable manner. Balls, which are not shown in Figs. X and XI are employed to effect the cutting. The mode of operation is as follows: When the cutting of the wrapper takes place the table 1) is lowered, and when the cutting has been effected the said table may be raised flush 0r substantially so with the suction plate and the bunch placed on the wrapper so that the suction plate and rolling table will together codperate to form a smooth surface upon which the rolling of the cigar may be effected.
